Title: Telescopic shock absorber with folding bellows - has automatic snap fit connection to engage bellows end on damper tube
Inventor: ENGEL MICHAEL DIPL ING
IPC: F16F9/38
Filed: 1991-11-14
Abstract: The telescopic shock absorber includes a folding bellows (6) set between the damping tube (3) and the emerging piston rod (4) to protect against dirt and/or wet. The end of the bellows on the side of the damping tube is fixed axially secured on the damping tube (3) or on a component (7) connected thereto by means of a snap connection which automatically locks when the piston rod (4) is inserted more or less fully into the damping tube- generally during the first time. This end (61) of the bellows can have a ring part (62) widening out funnel-shaped towards the free end, and behind this either a rear cut ring groove (63) or several rear-cut sections evenly distributed round the inner circumference, whilst the damping tube has outwardly directed protrusions (71) for subsequent interaction. ADVANTAGE - Easy assembly.
Patent DE-4140255-A1 (DE)
IPC: B60K15/035
Filed: 1991-12-06
Abstract: Known ventilating devices have an adsorption filter (1) in communication with the atmosphere through a ventilating pipe (46) controlled by a stop valve (51). Control errors may unintentionally keep closed the tank ventilation valve (3) and stop valve, so that overpressure builds up in the fuel tank (2), in the pipes (8, 16) and in the adsorption filter, thus leading to their destruction. By appropriately designing the magnetic circuit (54) of the stop valve (51, 51') the pressure generated above a predetermined overpressure in the adsorption filter (1) is sufficient to open the stop valve (51, 51') and thus to relieve pressure before damages are caused. This new ventilating device is particularly useful for internal combustion engines in motor vehicles.
Patent DE-4142295-A1 (DE)
Title: Valve for maintaining constant control pressure in pneumatic circuit - has flexible panel with tongues with deflection which increases with increasing pressure
Inventor: KISKE SIEGFRIED DR
IPC: A61M16/00
Filed: 1991-12-20
Abstract: A valve (35) for maintaining a constant control pressure in a pneumatic switching circuit has a cylindrical body (36) in which a valve seat (37) is installed. The seat is sealed by a seal (32) made of an elastomeric material. This seal has a curved slot which extends through almost 360 deg. so that a circular disc is formed which is attached to the body of the seal by a narrow neck. The edge of this disc is supported on the valve seat (37). The disc is divided in sectors (31) by radial slots to form tongues which are attached to the disc near its outer edge. When subjected to a pressure the tongues are deflected in the direction of the flow. USE/ADVANTAGE - Compact constant pressure valve for low pressure.
Patent DE-4202874-A1 (DE)
Title: Quiescent current supply circuit for telecommunication terminal - is either installed as auxiliary equipment or integrated into receiving appts. which is switched on when incoming message is recognised
Inventor: DOLLINGER ULRICH
IPC: H04N1/00
Filed: 1992-02-03
Abstract: When an incoming signal, message or call is detected the mains voltage (J1,J2) is connected automatically by a bidirectional semiconductor switch (Q1) to a transformer (TR1) which feeds the operating voltage (J3,J4) to the controlled appts. The AC supply is isolated from the telephone line (J5-J8) by an opto-coupler (IC1) which can be shorted out by a manual switch (SW1). A first incoming signal switches on the appts. in readiness for a second signal to commence its operation. The circulating voltage reverts to the standby value as soon as the appts. has completed its work. USE/ADVANTAGE - With facsimile receiver, telephone answering machine, TV receiver, video recorder etc., current consumption is reduced automatically on standby, and risk of fire is minimised.

Patent DE-4204981-A1 (DE)
Inventor: GIESE PETER DR ING DR
IPC: F16C27/04
Filed: 1992-02-19
Abstract: In gearwheel change gears, the so-called loose wheels (8) are preferably mounted on the gear shaft (3) by means of needle cages (11) and can be coupled to the gear shaft (3) by means of a coupling element. When these loose wheels (8) are not loaded in the radial direction and turn at high speeds of rotation, there results the so-called loose wheel screeching. In order to avoid this loose wheel screeching, at least one of the needles (13) of said needle cage (11) is elastically prestressed in the radial direction between the corresponding running tracks (15, 16). For that purpose, at least one of the running tracks (15, 16) has at least in one section of its circumference an elastic bulge (20) that deviates from the circular shape.

Title: Absolute position encoder with coding element having absolute and incremental symbol patterns in parallel - has detector with sensors for recording two symbol patterns and discriminates relative phase position of encoder and detector
Inventor: MATSUMOTO TSUYOSHI
IPC: G01D5/245
Filed: 1992-03-25
Abstract: A single track absolute symbol pattern (P) on a coder element (A) is monitored by two groups of sensors (E1-E4,F1-F4), and a number sequence 0000101100111101 is formed by two types of minimal read units with a length lambda. The incremental symbol pattern (I) with arranged alternating divisions or read units is arranged parallel to a further symbol pattern (A), the repeated period of which in this case is equal to the length lambda. A detector (B) is provided with a first group of sensors (E1-E4) and a second such group (F1-F4), which are arranged with a grid dimension lambda and are phase-displaced with a phase difference corresp. to lambda/2 in relation to the first group of sensors. A discriminator switch circuit (C) receives the somewhat triangular waveform output signals from the sensors (S1,S2) as sine and cosine waves, compares the two waves, and then discriminates in real time which of the eight phase positions in each grid dimension lambda corresponds to the phase relation between the coder element and the detector. ADVANTAGE - Miniaturised absolute encoder using single track absolute symbol pattern, in which wirings and connections are simplified.

Title: Correcting long and short-term variations in operating parameters during film analysis using x-ray fluorescence analysis - measuring reference channel and sample intensities at start-up or after re-adjustment, and intensities of excitation beam stimulation intensity as well as measurement specimen intensity
Inventor: ESCHE HANS-JUERGEN DR ING
IPC: G01B15/02
Filed: 1992-08-07
Abstract: The method involves measuring the intensities of a reference specimen in each measurement channel as well as the measurement element on equipment turn-on or for each re-adjustment. The ratio KE = IE/IRef of the measurements is formed. For each visual analysis the intensities of the specimen and stimulating radiation are measured, and immediately before and/or after each specimen measurement the reference specimen intensity IRef' and the stimulation intensity are also measured. The measured values are used to determine the current intensity of the pure element IE' from IE' = IE - KE (IRef - IRef' ). This is then used with the corrected measurement specimen intensity to determine the thickness and/or composition of the specimen under analysis. USE/ADVANTAGE - For use in visual analysis using X-ray fluorescence analysis. The method enables both detection and correction of long-term and short-term changes.
